1963 Ranchero

Be sure your tire size is maximized for a slight top end assist. If running modern 13" tires, the profiles are typically much smaller diameter?circumference. 14" wheels with '70' series tires will lower cruise RPM a bit if absolute originality is flexible.

Other mods require more work: Swapping an Overdrive transmission is the best alternative. . Automatic OD's are outside my data base. 80's Mustang T5 manual is a favorite for early cars, again if absolute originality is flexible.

Maverick and rare early Mustang 8" rear ends with higher ratio's will semi-bolt right in . Rear end gearing can dramatically change cruise RPM but with 170/2Spd Fordomatic may have poorer drive-ability result.

That 63 Ranchero is sure a nice ride to have, my good friend has one with a 200 and he put in a c4 and it drives real well. How much increase in top end are you looking for?
 
drive line = not just motor but transmis rear gear, & tire sz. Use an online gear calculator to play (less expensively than buying/trying components) with what ur willing to do for what U wanna get. To me (an extra component as a 4WDer) its the reason behind automotive engineering. Google's ur friend~
